The second valve body 42 is closed on the first valve body 41 because the head of the washing water remaining in the storage tank 24 acting on the second and the negative pressure generated by the drainage of the washing water are larger. I do. Further, when the water level of the washing water decreases and reaches a predetermined water level, the weight of the first valve body 41 and the second valve body 42 and the weight of the first valve body 41 become smaller than the buoyancy of the float chamber of the first valve body 41. And the negative pressure generated by the head of the washing water remaining in the storage tank 24 acting on the second valve body 42 and the drainage of the washing water becomes larger. Is stopped.

When the small washing and the large washing are started, the float 33 of the ball tap 30 descends as the level of the washing water stored in the storage tank 24 decreases. When the float 33 descends, the body 31 of the ball tap 30
The diaphragm valve incorporated in the tank is opened, and the supply of the cleaning water to the water discharge pipe 22 and the overflow pipe 56 attached to the bowl 21a in the storage tank 24 is started.
Eventually, when the small washing and the large washing are completed and the washing water is stored in the storage tank 24, the level of the washing water in the storage tank 24 rises, and the float 33 of the ball tap 30 rises accordingly. When the water level of the cleaning water in the storage tank 24 rises to the water stop level WL, the float 33 of the ball tap 30 closes the diaphragm valve built in the main body 31 of the ball tap 30, and the supply of the cleaning water is stopped.

In the present embodiment, a so-called tightly-coupled low tank mounted on the rear upper portion of the toilet bowl 10 has been described. However, the present invention is not limited to this. The toilet 10 may also be a Japanese-style toilet or a urinal.

The ball tap mounting surface 24a does not need to be above the overflow surface OF, but may be above the water stop level WL.
It is not necessary to be above the water stop level WL as long as the structure is insulated from the cleaning water stored therein.

Then, the water storage tank 24 and the ball tap 3
